Chill Touch is not working properly. The "Chilled" status currently ends at the start of a chilled creatures turn, not at the start of the Casters turn. RAW, in 5e, the anti-healing debuff should last until the start of the turn of the Caster of the spell, not its target. This makes the anti-healing property nearly useless, and completely useless against Sorak's regeneration and ability "Call of the Night".
Edit: This appears to maybe be a 'sometimes' bug. When my cleric went immediately before the Sorak, the Chilled status remained and the regeneration was denied. However, multiple other turns for the Sorak's have started with the "
Chilled" message and the status ending, allowing them to heal. Will update here if I notice any other trends.
